Description:
Template file created byMicrosoft Excel, a spreadsheet program; contains default settings and layout properties for a macro-enabled spreadsheet; used to create a new macro-Enabled workbook (.XLSM file) that uses the Open XML format, which was introduced in Microsoft Office 2007.XLTM files can be opened in Excel 2007 or later for Windows, or by Excel 2008 or later for Mac. They may also be opened by previous versions of Excel with Open XML component support.

Technical Details:
The XLTM file type is primarily associated with 'Excel' by Microsoft Corporation.This is the new format for Microsoft Office documents.It is a combination of XML architecture and ZIP compression for size reduction.Microsoft promises the format will be open (published for anyone to use) and prior versions of Office, using components provided by Microsoft for Office 2000, XP, and 2003 will be available to perform document conversion. Remember that these are promises by Microsoft. We have yet to see the actuals. This format is not the same as the OpenDocument standard, also an XML-based standard being developed as a true open standard (see the OpenDocument Fellowship for more information).

Supported applications:
Microsoft Excel 2010, Microsoft Excel 2011
